Suppose that a manager is interested in estimating the average amount of money customers spend in her store. After sampling 36 transactions at random, she found that the average amount spent was $37.85. She then computed a 99% confidence interval to be between $32.89 and $42.81. Which statement gives a valid interpretation of the interval? O There is a 99% chance that the mean amount spent by all customers is between $32.89 and $42.81. O The store manager is 99%...

Your local Target store is interested to know how much money, on average, their customers spend each visit in the housewares department. They go back through their records and draw a sample of 450 people and calculate each customer's average spending on housewares. a) Identify the population, sample, parameter, statistic and variable for this example. b) Describe a situation in which you would calculate a parameter rather than a statistic . For the 1,000 samples, the following is a breakdown of how much...
